Answer:
Express 23175.4 in standard form
Step-by-step explanation:
First you need to simplify the left side of the equation to get
Then you add by two on both sides to get
Finally you divide by 2 on both sides to get
Answer:
The change in elevation is -134 ft
Step-by-step explanation:
Given;
initial depth of the submarine, d₁ = 235 ft
final depth of the submarine, d₂ = 101 ft
The change in the elevation of the submarine is given by;
Δd = d₂ - d₁
Δd = 101 ft - 235 ft
Δd = -134 ft
The change in elevation is negative because the submarine is moving closer to the surface.
Therefore, the change in elevation is -134 ft
Answer:
1 hour and 45 mins
Step-by-step explanation:
As mentioned,
Starting time = 2:30 PM
Ending time = 4:15 PM
The given time is in hours and minutes, to calculate the duration of movie, time should be converted into a same unite minutes.
1 hour = 60 minutes
Therefore,
2:30 = 2 hours and 30 mins = 2*60 + 30 mins = 150 mins
4:15 = 4 hours and 15 mins = 4*60 + 15 mins = 255 mins
The duration = Ending time - Starting time
=> 255 - 150
=> 105 mins
or
60 + 45
1 hour and 45 mins
Answer:
10. 0
11. -16
12. 2
13. 2
14. 3
15. 0
Step-by-step explanation:
10. (x+4)(x-4) --> x= 4, -4 --> 4 + (-4) = 0
11. 4(-4) = -16
12. 2(x-2)² --> x = 2
13. 2
14. x(x-3) --> x= 0, 3, 0+3=3
15. 0(3) = 0
